Description

The Performance Open Head has the stock seats and valves replaced with larger SI Valves brand seats and valves. The seats are cut to include multiple angles and then the valves are lapped for a better seal. We machine .050" off the head to increase the compression ratio, and then the head is hand ported to improve flow. The head comes assembled with rocker arm assembly and 32lb dual valve spring set installed.
